I would think if anything maybe slight gains/losses in velocity. Minuscule but to some those single digit fps seem important. I’m nowhere near capable enough to even notice and it’s probably mostly irrelevant unless your in a very competitive tightly regulated style of comp. I rarely hear of dogs from barrel
makers anymore. I’d not worry about a quality barrel spun on by a well known plumber. My worry lately has been my poor planning/terrible schedule and their backlogs. Judging from his pics Pat doesn’t have that same constraint. Hope you tag a few more monsters this season.
